ELECTRIC HEATER AND HUMIDIFIER.

applicati@ ined May: 1e,jia1i.l serial No. 839,080.

To all whom it may concern: Y j. Be it known that I, WILLIAM CLATr SMrrr'r, a citizen of the United States, and-a resi- This invention relates to electric heaters -and relates more particularlyrto a'combined *heater and humidifier whereby vaporis-gentionable dryness of air heated erated by the heating'elements of. the heater and caused to mix with the heated air so as to temper the same and prevent theobjecby airfordinary electric heater.

The invention has for its general objects to provide a combined heater and humidifier which 4is of comparatively simple and-inexpensive construction, reliable and eicientlin use and so designed thatI it does not necessitate y any changes `the standard constructionrof the electrical part of the device.

A further objectof the vinventionfiis the provision of a casing .or an electric heater which includes in its embodiment "a water jacket so related to the coils or heatingelc;Y

ments of the heaterthatithe water is gradw; ually vaporized and mixed with thelheated;

air passing through the heater so as to give the proper humidity to the air of the room in which the apparatus is in use.

With such objects in view, and others which will appear as the description proceeds, the invention comprises various novel features of construction and arrangement of parts which will be set forth with particularity in the following description and claims appended hereto.

In the drawing, which illustrates one embodiment of the invention and wherein similar characters of reference indicate corresponding parts in both the views, Figure l is a side view of the combined heater and humidier; and Fig. 2 is an end view with portions in section to illustrate the water jacket and its relation to the heating elements.

Referring to the drawing, A designates a base of any suitable design on which the electric heating elements in the form of coils or equivalent means B are suitably secured, the current being supplied by fiexible cord C which is connected with the heating coils in the usual manner.

` Specification of Letters Patent.

A casing D made of- Patcnted Oct. 20, 1914.

sheet or other metal is positioned on the base- A and is provided with a cap E having openings through which the heated air as- ;fcends. The casing-D is a hollow box-like body which is bottomless and tits the raised Aportion a of the .baseA, and any suitable lmeansllmay -be employed-for Securing the casing to the base. 1 :In the wallsof the casing B and 'adjacent thefbo'ttom'thereof are openingsd :forming .ain inlet means whereby ktheair enters-'the casing andvtravels up- ',wardly along the heating elements and esfcapes through the cap E. l The humidifyin of the air. is accomiphshediby surroun ing the casing D with a jacket E fwhichhas'its upper andlower portions "f and f 'connected with the. exterior of thef-casmg D by waterand vapor-tight oints, whereby, la Water` and vapor chamber 1s pro f1dedi entirely around thecasing ofv :the heater. lW'aterlis suppliedtolthis chamber Gv through a' "lii'ngtopening that is znormally closed-by-fa coverlor cap g, the level fof:-tl'1'e-v'vater-A being I visible at all times i through a gager-glass'H, andI at the bottom of theawaterfjaeketatlany desired-point is a pet i.oiii` ffl-lie .upper part; of the chamber Gr com- ;fmunicates with the interior of the casing D through openings or ports g', and adjacent these openings are plates g2 which serve to form guards to prevent water from passing out through the openings g and wetting the heating elements, as when the device is moved.

In operation the body of water surrounding the heating elements is brought to a high temperature so that vapor is generated. This vapor naturally rises and passes into the top of the casing D and mixes with the ascending air which is previously heated by passing along the heating elements, and as a consequence the vapor is mixed with the heated air and humidifies it so that it is in a more natural and beneiicial state for breathing.

It will be seen that the jacket being made of sheet metal and placed around the eX- terior of the casing does not materially add to the cost or complication of the electric heater and humidifier and at the same time the article is of pleasing and attractive appearance and possesses the advantages hereinbefore referred to. Very little attention is required, as the filling of the humidifier every few days is sufficient. s the humidi-I fier contains a body of water that entirely surrounds the casing there is an equal dis#i trihution of Weight7 so that the stability of the apparatus is in no way impaired. It is furthermore to be noted that the improvement resides entirely in the casing, which is so designed vthat'it can he substituted for the casings of electric heaters in present 'use er of standard design.
